摘要
将三油酸甘油酯、双油酸甘油酯、单油酸甘油酯和油酸甲酯按1∶1∶1∶3(摩尔比)混合好后,采用目前大生产常用的工艺技术路线对这四元混合油脂体系进行氧化亚硫酸化.实验结果发现:氧化过程稳定,氧化程度控制点的过氧化值(POV)重现性好;其氧化亚硫酸化产物批次间品质稳定性好,加脂效果优良.将液体猪油作为研究对象进行验证,表明该工艺技术思路完全可以推广应用于其它四元混合油脂(动植物油脂、双油酸甘油酯、单油酸甘油酯和相应动植物油的脂肪酸甲酯)体系的氧化亚硫酸化过程,对于显著改善氧化亚硫酸化动植物油批次间的品质稳定性有良好的借鉴作用.
The oil system of mixed four oils was obtained by mixing simply olein,dioleoylglycerol,glycerol monooleate and methyl oleate according to the corresponding molar ratio of 1∶1∶1∶3,and was oxidized and sulfonated by the technological route adopted frequently by factories.It shows stable oxidation process and good repeatability of peroxide value(POV);Meanwhile,the reaction product from the technological route of oxidation-sulfonation shows good stability of the batch and good fatliquoring performance.The verifying experiment based on liquid lard oil showed the technological route can be promoted to oxidation-sulfonation process of other oil system route of mixed four oils such as natural animal and plant oil,dioleoylglycerol,glycerol monooleate and fatty acid methyl ester of corresponding natural animal and plant oil,which sets a good example for keeping the stability of the batch based on oxidizing and sulfonating natural animal and plant oil.
